Squirrels are the acrobats of the animal world—leaping through trees, stealing birdseed, and charming humans with their fluffy tails. But beneath that cute and clever exterior lies a surprising question: are squirrels actually rodents? Most people don’t lump them in with rats and mice, but science says otherwise. In this post, we’ll dig into the biology, bust some myths, and settle the debate once and for all.

What Makes a Rodent a Rodent, Anyway?

Rodents are mammals belonging to the order Rodentia, the largest group of mammals on Earth. What defines a rodent is one key feature: a pair of continuously growing incisors in the upper and lower jaws. These teeth never stop growing, so rodents must gnaw constantly to keep them in check. Rodents are typically small, adaptable, and have sharp senses—traits that make them highly successful in various environments. Some well-known rodents include rats, mice, beavers, hamsters, and guinea pigs.

Squirrels Under the Microscope

Scientific Classification:

Squirrels belong to the order Rodentia and the family Sciuridae, which scientifically places them within the rodent family tree. This family also includes chipmunks, prairie dogs, and marmots. With more than 200 species around the world, squirrels are a diverse and adaptable group. Despite their unique behaviors and appearance compared to rats or mice, they are genetically linked to their rodent relatives in undeniable ways.

Those Famous Teeth:

Like all rodents, squirrels have continuously growing incisors—sharp front teeth that must be kept in check by regular gnawing. These teeth can grow several inches per year, so chewing is essential for survival. They’ll gnaw on nuts, bark, twigs, and even manmade objects like wires. This dental trait is a key indicator that squirrels are true rodents.

Lifestyle & Habitat:

Tree squirrels are the most common, known for building nests (called dreys) high up in trees and navigating their surroundings with impressive agility. They use their long tails for balance and communication. In contrast, ground squirrels dig burrows and live more traditionally “rodent-like” lives underground. Squirrels have adapted to forests, cities, and even mountainous regions, showing just how versatile their lifestyles can be.

Diet & Foraging:

Squirrels are primarily herbivores and feed on nuts, seeds, fruits, fungi, and various plant material. One of their most fascinating behaviors is scatter hoarding—burying food across many locations to retrieve later. Their spatial memory is highly developed, allowing them to recover a large percentage of their hidden caches. Forgotten seeds often grow into new plants, making squirrels accidental forest gardeners.

Types of Squirrels:

There are three main types of squirrels: tree squirrels, ground squirrels, and flying squirrels. Tree squirrels are commonly seen in wooded and urban areas. Ground squirrels live in burrows and display more social and territorial behaviors. Flying squirrels, despite the name, glide through the air using a special membrane called a patagium—allowing them to travel distances of over 100 feet between trees.

Intelligence & Behavior: 

Squirrels are known for their clever problem-solving skills. For example, they often fake burying nuts to deceive watching predators or competitors. They quickly learn how to access bird feeders and navigate obstacles. Their ability to adapt and outsmart threats shows a level of intelligence not commonly associated with rodents.

Global Presence:

Squirrels are found on every continent except Australia and Antarctica. From dense forests to city parks, their adaptability to different climates and ecosystems has helped them thrive across the globe. This wide distribution reflects their resilience and resourcefulness, making them one of the most successful rodent groups in the world.

Why Squirrels Don’t Feel Like Rodents

Despite their classification, squirrels rarely get the same reputation as rats or mice. Why? A few reasons. First, their appearance works in their favor—fluffy tails, bright eyes, and agile movements make them seem more like woodland fairies than pests. Second, squirrels are less associated with urban filth or disease than rats. And finally, their tree-dwelling lifestyle keeps them at a distance, literally and emotionally, from the negative stereotypes we attach to rodents. But scientifically? They’re still rodents, just with better PR.

Conclusion:

So, are squirrels rodents? Absolutely. They check every box: those signature teeth, a place in the Rodentia order, and behaviors that match their fellow gnawers. But their charm and unique lifestyle help them stand out from the rest. Next time you see one dashing across a power line or digging in your flower pot, you’ll know—you’re watching one of nature’s most likable rodents in action.

FAQs

Are squirrels harmful like rats or mice?

Generally, no. While they can cause damage (like chewing wires or nesting in attics), squirrels are less likely to spread disease or infest homes the way rats and mice do.

Do squirrels carry diseases?

They can carry parasites and diseases, but human transmission is very rare. They’re not considered a major health threat.

Why do squirrels chew on everything?

Their teeth never stop growing, so they gnaw on wood, wires, and other materials to wear them down.

Are flying squirrels real?

Yes! Flying squirrels glide using a skin flap called the patagium. They’re nocturnal and rarely seen during the day.

What’s the difference between squirrels and chipmunks?

Chipmunks are a type of ground squirrel, typically smaller with stripes. Both are in the Sciuridae family, making them rodent cousins.
